What is the best imaging modality to precisely localize the three-dimensional position of an impacted mesiodens (supernumerary tooth in the maxillary midline)?

Cone-beam computed tomography (CBCT)
Bitewing radiograph
Lateral cephalogram
Occlusal radiograph alone, with no 3D imaging needed

Show answer and explanation

Correct answer: A. Cone-beam computed tomography (CBCT)

CBCT provides precise three-dimensional localization of an impacted mesiodens relative to adjacent roots and anatomic structures, which is essential for surgical planning — far superior to any single 2D radiograph for determining the tooth's exact buccolingual and vertical position.
